  • the piston has a compressed air connection on one side for a control pressure, and on the other side is a device provided for generating a counter force, advantageously in the form of a compression spring.
  • the second piston of the double seat valve is on its second side with the environment connected in the manner that at a lower position of the piston rod with the both pistons vented the brake cylinder chamber via the ambient connection becomes.
  • the double-seat valve is advantageously closed in this lower position, so that the compressed air connection of the connecting line from the storage air tank to the double seat valve - or the line connected in parallel - of the brake cylinder pilot chamber is disconnected.
  • the double seat valve is opened, the Bremszylindervor faced separated from the environment by the second piston, so that compressed air through the double seat valve in the Bremszylindervor Tavern breed can flow.
  • the double-seat valve is designed as a plunger valve and in the closing direction with a compression spring and in the opening direction by the piston rod of the control valve loaded.
  • the valve described above which is the connection between the main air line and double seat valve controls, designed as a plunger valve.
  • this can also be done in Closing direction with a compression spring and in the opening direction by the piston rod to be burdened.
  • the above-described, specially designed control member comprises in an advantageous Embodiment of the invention a piston rod with an axial bore, a piston, a partition, a second partition and a valve.
  • a bypass is formed for bridging the partition wall.
  • On the Valve-facing side of the piston is advantageously a compressed air connection to Bremszylindervor Kunststoffsch formed, and on the valve side facing away of the piston is a device for generating a counterforce, advantageously in shape a compression spring arranged.
  • the compressed air connection for the control pressure can be connected via the valve with the main air line.
  • the piston rod is like that arranged so that it passes from the valve through the two partitions to the piston.
  • valve as a closing direction with a Compression spring and in the opening direction by the piston rod loaded plunger valve educated.
  • vent valve - opposite the environment opens and closes
  • the vent valve is additional the passage to the environment then free when the Bremszylindervor Tavernauer via the environmental connection in the control valve at a lower position of Piston rod is vented with the two pistons. Therefore, it is particularly advantageous the vent valve also formed as a plunger valve, in the opening direction at least indirectly loaded by the control pressure and in the closing direction in particular with a compression spring.
  • the vent valve essentially the same structure as the valve in the parallel line between the storage tank or have the double seat valve and the main air line, with a piston - loaded by the control pressure and the other side by a device for generating a counterforce - and with a piston rod, the in particular held closed by the compression spring valve accordingly high control pressure and thus the connection of the Bremszylindervor Kunststoff to the environment releases.
  • Particularly advantageous may also be in the compressed air connection between supply air tank and double seat valve an additional valve and / or an orifice be switched. Furthermore, it is advantageous, the compressed air connection of the main air line by the control member to the control chamber particularly pressure-lossy to carry out, in particular by the design of the bypass with a tight Flow cross section. Furthermore, can be advantageous in the compressed air connection between the control member and the control chamber, a valve and / or an orifice be switched. The advantages of the latter embodiments are below in the description of a braking operation based on an inventive Embodiment of the control device explained.
